What's the difference between pilots flying and pilots not flying?

PF is the main monitoring instrument for flight control aircraft, which is relatively easy. If the flight conditions are good and there is no icing turbulence, all the way to skc.

PNF will assist PF in flight radio list, weather changes during navigation, airport information where the weather will land, etc. In order to help PF, it is also important to remember to call deviation when PF concentrates on controlling the aircraft! ! !
